Hoping to get a bit of help with a problem I am having with crawler.js

The script runs, the images crawl across the screen however, I have 7 images to scroll through and hoping to add many more, my client is hoping for about 35, but at the moment, when the crawler starts it shows the first 3 images, then back to the start but then only scrolls through 6 or the 7 images. Is there a limit to the number of images that can be used?
